Advantages

Excellent Color Performance
- Vivid Greenish – Yellow Hue: It presents a bright greenish – yellow color with high saturation, which can provide eye – catching color effects for various applications, making products more attractive.
- High Color Strength: With strong tinting power, only a small amount of Pigment Yellow 138 is needed to achieve the desired color depth, helping to reduce production costs.
Outstanding Fastness Properties
- Excellent Light and Weather Resistance: It has a light fastness rating of 7 – 8 and can maintain its color stability when exposed to sunlight and outdoor environments for a long time, with little fading or discoloration1. This makes it suitable for applications where long – term outdoor use is required, such as automotive coatings and architectural coatings.
- Good Chemical Resistance: It has excellent resistance to acids, alkalis, and various organic solvents, with a resistance level of 4 – 5. It can maintain its color and performance in different chemical environments, suitable for industrial coatings that may come into contact with chemical media.
High Thermal Stability: It can withstand high temperatures of up to 290 – 300°C, depending on the specific application environment. It has good heat stability in plastics such as HDPE, which can meet the high – temperature requirements during the processing of some plastics and prevent thermal decomposition or hue shift.
Good Compatibility and Migration Resistance: It has good compatibility with a variety of resins and solvents and shows excellent migration resistance in plastics, inks, and coatings. It will not migrate or bleed, ensuring the color stability and quality of the final product.
Wide Application Range: It is suitable for use in various industries, including coatings, plastics, inks, and textile printing and dyeing. It can meet the color – matching needs of different materials and processes and has good dispersibility and stability in different application systems.
Environmental Friendliness: Some Pigment Yellow 138 products comply with relevant environmental protection standards, such as EU RoHS and EN71 – 3 (toy safety standards), and can be used in environmentally friendly packaging, toys, and other products.
